The present embodiment can also be preferably the function of the status information increase abnormality alarm of groove tank.Specifically by realizing with under type:
Be previously stored with described for responding to the threshold value of the groove can-like state of the sensor sensing of the state of described groove tank, at least one namely in temperature threshold, humidity threshold, weight threshold, threshold pressure, gas concentration threshold, level threshold in processor 202;
Processor 202 obtain from data acquisition module 208 sensor sensing that vehicle administrating system comprises to the status information of groove tank, this status information can be temperature value, humidity value, gravimetric value, pressure values, gas concentration value, at least one in level value, then the status information of obtained groove tank is carried out with corresponding threshold value respectively contrasting (as: temperature value of acquisition is compared with the temperature threshold prestored), judge whether the state of groove tank exceeds corresponding described threshold value, if, then control abnormality alarm module 203 and send abnormality alarm, to point out human pilot, groove tank is checked, and control GPRS data communication module 204 by the related information transmission of abnormality alarm to central server 205, according to the relevant information of abnormality alarm, comprehensive assessment is carried out to the driving behavior of human pilot to make central server 205, realize the management and control to driving behavior.
The present embodiment is by increasing the function of abnormality alarm to each groove can-like state induction, human pilot can be made to understand the state of article in transportation middle slot tank timely, and take corresponding treatment measures (check groove tank, adjust self driving behavior etc.) according to the change of article condition, can in the generation effectively avoiding security incident; By the abnormality alarm information of groove can-like state is uploaded to central server, center server can be made to understand the on-the-spot situation of transport timely, and centered by the driving behavior of server comprehensive assessment human pilot more comprehensively foundation is provided.
When the article of harmful influence transport vehicle transport are liquid, and liquid is not full of the situation of groove tank, and the nonstandard driving behavior in transportation more easily causes rocking of liquid, thus increases the probability causing security incident.Therefore, the present embodiment additionally provides following technical scheme:
When the article in groove tank are liquid, driving behavior managing and control system preferably can comprise: weight sensor, is used for responding to the weight of article in groove tank.
Tilt values preset range and the velocity amplitude preset range of vehicle traveling is previously stored with in processor.
Processor obtains the gravimetric value of the groove pot liquid that weight sensor senses from data acquisition module, whether be canful according to the liquid that gravimetric value judges in groove tank, if not, then from tilt values computing module, obtain the current tilt values of vehicle, and from GPS locating module, obtain the current velocity amplitude of described vehicle, contrast corresponding respectively to obtained tilt values and velocity amplitude with tilt values preset range and velocity amplitude preset range, judge tilt values whether in tilt values preset range, and judge velocity amplitude whether in described velocity amplitude preset range, if tilt values is in tilt values preset range, and velocity amplitude is in velocity amplitude preset range, then control abnormality alarm module and send abnormality alarm, to point out the driving behavior of human pilot specification self, and control GPRS data communication module by the related information transmission of abnormality alarm to central server, according to the relevant information of abnormality alarm, comprehensive assessment is carried out to the driving behavior of human pilot to make central server, realize the management and control to driving behavior.
Above-mentioned driving behavior managing and control system, by the weight of weight sensor induction groove pot liquid, then the liquid held the whether canful of groove tank is judged, if not canful, then illustrate liquid in groove tank very easily due to Vehicle Speed how soon, the situation such as groove tank tilt values is excessive and shaking, now pay particular attention to the driving behavior of human pilot.Pre-setly be in tilt values preset range outside safe range and velocity amplitude preset range, then the tilt values calculated and the velocity amplitude collected are compared with corresponding preset range respectively, if the tilt values that vehicle is current and velocity amplitude are all in corresponding preset range, then illustrate that current driving behavior is nonstandard for groove tank actual conditions, there is larger potential safety hazard, now control abnormality alarm module to report to the police, and warning information is uploaded to central server, with while the driving behavior of prompting human pilot specification self, centered by server comprehensive assessment is carried out to the driving behavior of human pilot reference is on the one hand provided.
It should be noted that, mutually mate between the tilt values preset range set in advance and velocity amplitude preset range, in simple terms, namely when the degree of tilt of vehicle and speed all reach certain value, even if tilt values separately, it does not reach degree of tilt threshold value, if but travel speed is very fast, current tilt angle value also can increase the hidden danger of the security incidents such as vehicle rollover in conjunction with velocity amplitude, therefore on the basis that tilt values is passed judgment on separately, scheme tilt values being passed judgment on to driving behavior in conjunction with velocity amplitude can be increased.In the present embodiment, the upper limit of tilt values preset range is preferably less than described degree of tilt threshold value.
